Concept explainers
Interpretation: Whether Dalton’s model of the atom included protons, neutrons and electron inside the atoms or not should be discussed.
Concept introduction:
Dalton’s atomic theory was proposed by John Dalton. Dalton’s model explained important observations. For example: the law of constant composition.
Answer to Problem 4RQ
Dalton atomic theory was discovered in the year
Explanation of Solution
John Dalton, British teacher and scientist, explained concepts behind most natural materials are mixtures of pure substance, pure substances are either elements or combinations of elements called compound. Summarized explanation of these concepts is termed as Dalton’s atomic theory.
Dalton's model of the atom did not include neutrons, protons, and electrons inside the atoms. The reason behind this is that these particle (neutrons, protons, and electrons) were not discovered until the year
In Dalton’s time, no one knew about neutrons, protons, and electrons.
